Die Neuregelung der Qualitätssicherung für Hormone und Pharmaka gemäß den Qualitätssicherungsrichtlinien der Bundesärztekammer (Rili-BÄK) unterliegt einer intensiven Diskussion, besonders in Hinsicht auf die Praktikabilität Für die ärztlichen Laboratorien und die Diagnostikahersteller ergeben sich erhebliche Veränderungen, die aufgezeigt werden.
Im folgenden Beitrag werden die Möglichkeiten der Bildung des Progressivs im Aja dargestellt sowie die zur Bildung des Progressivs verwendeten Formen in ihrer Grammatikalisierungskette vorgestellt. Das Aja gehört zu einer Gruppe von Sprachen/Dialekten, die lange Zeit unter dem Begriff "Ewe" zusammengefaßt wurden, in jüngster Zeit aber auch als Gbe(-Kontinuum) bezeichnet werden. Dabei ist "Gbe" ein in allen sprachlichen Einheiten des Kontinuums anzutreffendes Lexem mit der Bedeutung "Sprache".
A new method of measuring quality factors in cavities is presented. This method is well suited to measure quality factors in undamped cavities as well as in heavily damped cavities, and in addition this method provides a possibility of separating modes and measuring quality factors especially in cases of overlapping modes. Measurements have been carried out on HOM-damped cavities for the DESY/THD linear collider project. Results are presented.
Damping cells for the higher order modes are necessary for the S-band linear collider to minimize BBU (Beam-Break-Up). The construction of the damper cells has to take into account the different field geometries of the higher order modes. So two different types of dampers have been designed: a wall slotted an an iris slotted cell. In order to optimize the two types of damping cells with respect to damping strength, impedance matching between coupling system and waveguide dampers and between damping cell and undamped cells and the tuning system, damping cells of both types have been built and examinated.
Valenz und Relevanz - eine informationsstrukturelle Erklärung für "obligatorische" Adverbiale
(1995)
Adverbiale stellen ein Problem fü r die Beschreibung der Valenz bzw. der Argumentstruktur von Verben dar, da sie sowohl als Ergänzungen (Argumente) wie auch als freie Angaben (Adjunkte) auftreten können. Die Obligatorik bietet keine Möglichkeit, Ergänzungen von Angaben zu unterscheiden, da Ergänzungen sowohl obligatorisch als auch fakultativ sein können.

[Kongreßabstract] Opus®-Magnum, ein neues Analysensystem für Immunoassays. Ein Methodenvergleich
(1995)
In this paper I show that Clitic Climbing (CC) in Spanish and Long Scrambling (LS) in German (and Polish) are (im-)possible out of the same environments. For an explanation of this fact I propose a feature-oriented analysis of incorporation phenomena. The idea is that restructuring is a phenomenon of syntactic incorporation. In German and Polish, Agro incorporates covertly into the matrix clause and licenses LS out of the infinitival into the matrix clause. Similarily the clitic in Spanish, which is analysed as an Agro-head, incorporates into the matrix clause. I argue that this movement is necessary for reasons of feature-checking, i. e. for checking of an [+R]- or Restructuring-feature. In section 2 I discuss several differences between CC and LS. For example, the proposed analysis correctly predicts that clitics in contrast to scrambled phrases are subject to several serialization restrictions. Throughout the paper I use the term restructuring only in a descriptive sense, in order to describe the phenomenon in question.
Thema dieses Aufsatzes sind die Methoden der Datenerhebung für syntaktische Untersuchungen und deren Auswirkungen auf die Ergebnisse dieser Untersuchungen. Die Wahl der Datenbasis ist selbst schon bestimmt durch bestimmte theoretische Positionen, Einstellungen gegenüber dem Forschungsgegenstand und durch bestimmte Erkenntnisinteressen. Es soll hier also nicht der Eindruck erweckt werden, als wäre die Datenbasis per se für die "Folgen" verantwortlich.
Redekommentierende Einschübe
(1996)
Das Thema dieses Aufsatzes sind redekommentierende Einschübe. Zunächst gilt es zu klären, was unter "Einschub" verstanden werden soll. Einschub verwende ich hier weitgehend gleichbedeutend mit Parenthese. Parenthesen werden jedoch manchmal als "Schaltsätze", also als eingeschobene Sätze, definiert. Einschub ist hier ein weniger vorbelasteter Terminus.

Given x small epsilon, Greek Rn an integer relation for x is a non-trivial vector m small epsilon, Greek Zn with inner product <m,x> = 0. In this paper we prove the following: Unless every NP language is recognizable in deterministic quasi-polynomial time, i.e., in time O(npoly(log n)), the ℓinfinity-shortest integer relation for a given vector x small epsilon, Greek Qn cannot be approximated in polynomial time within a factor of 2log0.5 − small gamma, Greekn, where small gamma, Greek is an arbitrarily small positive constant. This result is quasi-complementary to positive results derived from lattice basis reduction. A variant of the well-known L3-algorithm approximates for a vector x small epsilon, Greek Qn the ℓ2-shortest integer relation within a factor of 2n/2 in polynomial time. Our proof relies on recent advances in the theory of probabilistically checkable proofs, in particular on a reduction from 2-prover 1-round interactive proof-systems. The same inapproximability result is valid for finding the ℓinfinity-shortest integer solution for a homogeneous linear system of equations over Q.
"Mundarten werden von den Bauern im Kreis der Familie gesprochen, sie haben einen beschränkten Kommunikationsradius, ihre situative Verwendbarkeit ist eingeschränkt, sie stellen im Sinne Bernsteins einen restringierten Code dar." Solche und ähnliche Definitionsaspekte für den Begriff Dialekt finden wir immer wieder. Für Teile des deutschen Sprachgebietes sind sie auch adäquat. Die Mundarten sind dort sozial abgewertet und werden durch regionale Umgangssprachen, als Mischformen zwischen Dialekt und Hochsprache, zurückgedrängt. In der deutschsprachigen Schweiz ist dies keineswegs der Fall: Als Rolf Zinkernagel, Professor am Institut für experimentelle Immunologie der Universität Zürich, am 7. Oktober der Nobelpreis für Medizin zugesprochen wurde, war das eine der Hauptmeldungen in den Abendnachrichten. Das Interview, in dem er seine Freude über die Verleihung ausdrückt und in dem er allgemein Forschungsvorgehen erklärt, wird ganz selbstverständlich in der Mundart geführt.
Preferences and defaults for definiteness and number in japanese to german machine translation
(1996)
A significant problem when translating Japanese dialogues into German is the missing information on number and definiteness in the Japanese analysis output. The integration of the search for such information into the transfer process provides an efficient solution. General transfer includes conditions to make it possible to consider external knowledge. Thereby, grammatical and lexical knowledge of the source language, knowledge of lexical restrictions on the target language, domain knowledge and discourse knowledge are accessible.
The behavior of hadronic matter at high baryon densities is studied within Ultrarelativistic Quantum Molecular Dynamics (URQMD). Baryonic stopping is observed for Au+Au collisions from SIS up to SPS energies. The excitation function of flow shows strong sensitivities to the underlying equation of state (EOS), allowing for systematic studies of the EOS. Dilepton spectra are calculated with and without shifting the rho pole. Except for S+Au collisions our calculations reproduce the CERES data.
An anaphor resolution algorithm is presented which relies on a combination of strategies for narrowing down and selecting from antecedent sets for re exive pronouns, nonre exive pronouns, and common nouns. The work focuses on syntactic restrictions which are derived from Chomsky's Binding Theory. It is discussed how these constraints can be incorporated adequately in an anaphor resolution algorithm. Moreover, by showing that pragmatic inferences may be necessary, the limits of syntactic restrictions are elucidated.

In this short note on my talk I want to point out the mathematical difficulties that arise in the study of the relation of Wightman and Euclidean quantum field theory, i.e., the relation between the hierarchies of Wightman and Schwinger functions. The two extreme cases where the reconstructed Wightman functions are either tempered distributions - the well-known Osterwalder-Schrader reconstruction - or modified Fourier hyperfunctions are discussed in some detail. Finally, some perpectives towards a classification of Euclidean reconstruction theorems are outlined and preliminary steps in that direction are presented.
Dieser Beitrag soll die fossilierte Lernervarietät darstellen, wie sie von vielen in der Deutschschweiz assimilierten Welschen gesprochen wird. Obwohl der deutsch-französische Sprachkontakt in der Schweiz schon lange intensiv ist, ist diese Varietät noch kaum beschrieben, während das Verhältnis von Welsch- und Deutschschweizern in Untersuchungen zur viersprachigen Schweiz oft thematisiert wird. Die folgende Auswahl soll nur einen Einblick geben in diese Fragestellungen: Die Einstellung der Romands zum Schweizerdeutschen und ihre Bereitschaft, die Mundart zu lernen, untersucht G. Lüdi (1992), U. Windisch u.a. (1994) dokumentieren die Alltagsbeziehungen zwischen Romands und Deutschschweizern, B. Py (1996) zeigt die Funktion des Code-Switching in bi- oder multilingualen Gemeinschaften, darunter viele Beispiele von Romands. Mehrfach untersucht wurde die Sprachwahl und das Sprachverhalten in den zweisprachigen Städten Biel und Fribourg (u.a. C. Brohy (1992); G. Kolde (1981)). In den letzten Jahren sind einige Arbeiten zur schweizerdeutschen Lernervarietät der italienischen, griechischen und türkischen Immigranten erschienen (G. Berruto und H. Burger (1985); W. de Jong (1986), S. dal Negro (1993); I. Werlen (1986)). Zur dialektalen Varietät der Welschen hingegen ist mir einzig die Arbeit von I. Werlen (1991) bekannt. Im Rahmen eines Projekts des Phonogrammarchivs der Universität Zürich zu den Sprachvarietäten in der Stadt Bern wurde auch eine Aufnahme eines Welschen realisiert. Diese Aufnahme möchte ich hier präsentieren.
An den Studiengängen der Abteilung für Germanistik und Deutsch als Fremdsprache unserer Universitäten nimmt das Fach „Deutsche Grammatik“ einen wichtigen Platz ein. Zu beobachten ist dabei, dass die Studierenden der grammatischen Strukturen des Deutschen sowohl in morphosyntaktischer und funktioneller Hinsicht nicht auf erforderlichem Niveau beherrschen. Dabei soll besondere Kraft darauf verwendet werden, die morphosyntaktischern Kenntnisse in aktive Sprachfähigkeit umzusetzen. Ziel dieser Arbeit ist, Gedanken und Vorschläge zu entwickeln, wie der Unterricht hinsichtlich unserer Zielgruppe fruchtbar, besonders für die funktionelle Beherrschung der deutschen Grammatik gestaltet werden kann.
Due to the additional need of very short bunches for the FEL operation with the TESLA-machine strong wakefield effects are expected. One third of the total wakefield energy per bunch is radiated into the frequency region above the energy gap of Cooper pairs in superconducting niobium. The energy of the cooper pairs in superconducting niobium at 2 K corresponds to a frequency of 700 GHz. An analytical and experimental estimation for the overall energy loss of the FEL bunch above energy gap is presented. The analytical method is based on a study from R. B. Palmer [1]. The results of the wakefield estimations are used to calculate possible quality factor reduction of the TESLA cavities during FEL operation. Results are presented.
Syntactic coindexing restrictions are by now known to be of central importance to practical anaphor resolution approaches. Since, in particular due to structural ambiguity, the assumption of the availability of a unique syntactic reading proves to be unrealistic, robust anaphor resolution relies on techniques to overcome this deficiency. In this paper, two approaches are presented which generalize the verification of coindexing constraints to de cient descriptions. At first, a partly heuristic method is described, which has been implemented. Secondly, a provable complete method is specified. It provides the means to exploit the results of anaphor resolution for a further structural disambiguation. By rendering possible a parallel processing model, this method exhibits, in a general sense, a higher degree of robustness. As a practically optimal solution, a combination of the two approaches is suggested.
This paper proposes a new approach for the encoding of images by only a few important components. Classically, this is done by the Principal Component Analysis (PCA). Recently, the Independent Component Analysis (ICA) has found strong interest in the neural network community. Applied to images, we aim for the most important source patterns with the highest occurrence probability or highest information called principal independent components (PIC). For the example of a synthetic image composed by characters this idea selects the salient ones. For natural images it does not lead to an acceptable reproduction error since no a-priori probabilities can be computed. Combining the traditional principal component criteria of PCA with the independence property of ICA we obtain a better encoding. It turns out that this definition of PIC implements the classical demand of Shannon’s rate distortion theory.
Thermodynamical variables and their time evolution are studied for central relativistic heavy ion collisions from 10.7 to 160 AGeV in the microscopic Ultrarelativistic Quantum Molecular Dynamics model (UrQMD). The UrQMD model exhibits drastic deviations from equilibrium during the early high density phase of the collision. Local thermal and chemical equilibration of the hadronic matter seems to be established only at later stages of the quasi-isentropic expansion in the central reaction cell with volume 125 fm 3. Baryon energy spectra in this cell are reproduced by Boltzmann distributions at all collision energies for t > 10 fm/c with a unique rapidly dropping temperature. At these times the equation of state has a simple form: P = (0.12 - 0.15) Epsilon. At SPS energies the strong deviation from chemical equilibrium is found for mesons, especially for pions, even at the late stage of the reaction. The final enhancement of pions is supported by experimental data.
We analyze the reaction dynamics of central Pb+Pb collisions at 160 GeV/nucleon. First we estimate the energy density pile-up at mid-rapidity and calculate its excitation function: The energy density is decomposed into hadronic and partonic contributions. A detailed analysis of the collision dynamics in the framework of a microscopic transport model shows the importance of partonic degrees of freedom and rescattering of leading (di)quarks in the early phase of the reaction for E >= 30 GeV/nucleon. The energy density reaches up to 4 GeV/fm 3, 95% of which are contained in partonic degrees of freedom. It is shown that cells of hadronic matter, after the early reaction phase, can be viewed as nearly chemically equilibrated. This matter never exceeds energy densities of 0.4 GeV/fm 3, i.e. a density above which the notion of separated hadrons loses its meaning. The final reaction stage is analyzed in terms of hadron ratios, freeze-out distributions and a source analysis for final state pions.
High perveance negative ion beams with low emittance are essential for several next generation particle accelerators (i. g. spallation sources like ESS [1] and SNS [2]). The extraction and transport of these beams have intrinsic difficulties different from positive ion beams. Limitation of beam current and emittance growth have to be avoided. To fulfill the requirements of those projects a detailed knowledge of the physics of beam formation the interaction of the H- with the residual gas and transport is substantial. A compact cesium free H- volume source delivering a low energy high perveance beam (6.5 keV, 2.3 mA, perveance K= 0.0034) has been built to study the fundamental physics of beam transport and will be integrated into the existing LEBT section in the near future. First measurements of the interaction between the ion beam and the residual gas will be presented together with the experimental set up and preliminary results.
The knowledge of the build up time of space charge compensation (SCC) and the investigation of the compensation process is of main interest for low energy beam transport of pulsed high perveance ion beams under space charge compensated conditions. To investigate experimentally the rise of compensation an LEBT system consisting of a pulsed ion source, two solenoids and a drift tube as diagnostic section has been set up. The beam potential has been measured time resolved by a residual gas ion energy analyser (RGA). A numerical simulation for the calculation of self-consistent equilibrium states of the beam plasma has been developed to determine plasma parameters which are difficult measure directly. The results of the simulation has been compared with the measured data to investigate the behavior of the compensation electrons as a function of time. The acquired data shows that the theoretical rise time of space charge compensation is by a factor of two shorter than the build up time determined experimentally. In view of description the process of SCC an interpretation of the gained results is given.
